CoAP specifies mainly protocol security based on the transport layer through DTLS.
OSCORE (Object Security for Constrained RESTful Environments) has been recently defined to support end-to-end protection of RESTful interactions over the CoAP protocol. It was designed for constrained devices and networks supporting a range of proxy operations, including translation between different transport protocols.
The main challenge presents in OSCORE is the establishment and exchange of pre-shared keys required to protect data. For that, this paper defines how use an optimised version of SRAM-based PUF (Physical Unclonable Functions) for a secure authentication, key establishment and exchanging model.
Ideas:
and 6TiSCH, an efficient protocol stack that runs over IEEE 802.15.4 radios, what are they using?
6TiSCH, an efficient protocol stack that runs over IEEE 802.15.4 radios, not mentioned in the paper.
They used SRAM PUF for authentication by storing CRPs on server
In my work, we will use SRAM PUF to build a root of trust, and generate keys which can be shared
